In my opinion, this Neighborhood has two areas, delimited by Mission St. Mission St. is full of Mexican restaurants and clubs. People there are mostly Mexican or Latin in general. The street itself is noise and dirty.The lower area ( Shotwell, South Van Ness, Capp, …) is a little more of the Missionst style, but I guess it is a little more dirty and houses’ are more neglected.
The upper area ( Valencia st, Guerrero St, Dolores St, and Church St) looks different. Streets are clean, there is not much noise and the diversity is higher in terms of people and restaurants. The best street to go eat is Valencia st, from 16th to 23 rd street you have plenty of restaurants (Japanese, Peruvian, Spanish, Mexican, Chinese, Italian, French…)And of course the best of the Mission is the weather. It is sunny most of the time; sometimes it’s windy but not too often. There are the perfect conditions to enjoy the Park, Dolores Park, which is perfect to go to hang out with friends or by yourself, to read, to play tennis, basketball…
I would also say that there are a lot of coffee shops with free internet wireless connection all around the area.
