Update
I came back home today from Hanoi and I have to say Hanoi is a really cool place. So far Vietnam is my second favorite place I've traveled after Japan. Considering how cheap it is there and how expensive it is in Japan, Vietnam might be better in some ways. My friend and I stayed at a hostel in Hanoi for 2 days then stayed at Cat Ba island for four, then went back to Hanoi and stayed at the same hostel two more days. In Hanoi, we mostly explored museums and parks, tried to eat as many different things as possible, and at night we went out to drink and talk to people. The focus was on food though.
At Cat Ba, we did the package tour on a boat around Lan Ha Bay. Went to Monkey Island, Kayaking, etc. On the Island I mostly had fun driving a motorcycle and exploring. This was my first time driving a motorcycle so that was cool. Cat Ba doesn't have a whole lot to do it seems though. The food wasn't as great as Hanoi and it was a bit more touristy. The place we stayed at was a bit lacking in facilities so the stay was a bit uncomfortable and the weather was cloudy and chilly at times, but overall I had a good time. We met some cool people at the hostel and we ended up partying with them back in Hanoi last night.
My overall impression is that Vietnam is way more chill, less money hungry, and "harmonious" than some of the other poorer developing countries I've been to. Instead of having a cut throat mentality of trying to scam every tourist and trying to milk as money as they can out of everything, things seemed by the book for the most part. I worried about being scammed or having extra "secret" charges put on top of things but nothing like that happened. The worst thing that happened was that this lady at Cat Ba charged people 5000 VDN to use the bathroom but that's like 25 cents so I just paid her. Another guy tried to charge us to chill at the beach so we just went to another beach that was free. In a few cases people gave us free stuff. Because it was the Lunar New Year holiday, people were eating this rice cake thing and a couple times people just offered them to us. It was pretty good too. I had a foot massage my first night in Hanoi and the guy threw in a bit of a shoulder massage and cracked my back for free too. Compared to the last country, the Philippines, it was quite nice.
Despite being "poor" and underdeveloped, I didn't see poverty or struggle like one expects from such a country. I barely saw any homeless people. Everybody seemed to be doing alright in terms of surviving even if it meant they didn't have modern comforts. People seemed happy and content. Barring the few homeless people, nobody looked like they were starving.
Vietnam felt much safer too. People warned me about pickpockets so I was vigilant but nothing out of the ordinary happened. This one shifty looking dude kept eyeing my wallet as I took it out to pay for something but that was about it. On my last night out in Hanoi, I was approached by this guy who kept trying to get me to follow him to a brothel, telling me that the women are pretty and that I wouldn't have to pay if I didn't like any of them. Even showed me photos of a few of them. I kept turning him down and he changed his pitch to weed lol. That tempted me a bit but I couldn't trust the guy and I felt vulnerable being so drunk and high (balloons). I heard a horror story of a guy who followed a girl back to her place only find a bunch of guys waiting for him so they can extort money out of him. Better safe than sorry I guess.
Night life in Hanoi is quite lively and maybe even crazier than Seoul. It seems constantly busy and a bit too much for me. Balloons with some sort of gas seem popular there which I tried and it messed me up. The women are attractive although I still think Korean women are hotter. Viet women are definitely more attractive than Filipinos and seem much more conservative. I met a couple girls but I didn't get laid due to schedule conflicts or perhaps my weak ass game. It also seems like a good place to meet western backpackers as well. I haven't seen so many white women in a while. Another good thing about Vietnam is that people are overall smaller so I didn't feel like such a manlet around the locals.
The best part was the food. From what I hear, it's even better in other places of the country but I was nonetheless blown away. On top of that it's so cheap. The most memorable thing for me was Bun Cha and Sen Buffet. Thanks to
@Jake the Muss for that recommendation. I tried croc and sparrow meat for the first time at the buffet as well. To live up to my sherdog gimmick, I wanted to try Vietnamese pigeon, but the restaurant I went to ran out of it when I went. I could've eaten it at another time but I was always too full from something else.
So yeah, Hanoi is chill. I remember one poster said Hanoi is just like any other city but I really liked it. I would like to check out other places in Vietnam now though. One week wasn't enough. I would recommend Vietnam and Hanoi to anybody interested in traveling.
