Williams is one of the largest bars in Uptown. It is multiple levels, with pool tables, free popcorn, and they are the only peanut bar (free) I know of (although you are limited to the basement if you choose to partake in these tasty morsels). Its usually packed later in the week and on the weekends, which makes it a little hard to get a drink, but if you head back to the pool tables, a waitress might be by soon.
They also usually have a beer tub when you walk in. Music is usually top 40 and more mainstream. During the summer they have a small outdoor patio along the sidewalk great for people watching. The crowd is usually well-hipply dressed and 22-28 years old. For any night, Williams is a safe bet because they are almost always packed and one of the best spots to play pool in uptown.
