There was a conference of over 1000 students at Yale. Most students stayed at the Omni; they were extremely accomodating. We walked everywhere even though it was cold. Try S'wings and their death wing! We ate there three times for wings and their great fries/sauce. The guys who work there are awesome! I wasn't a fan of the buffett at Bangkok Gardens. Club Alchemy has two nice dance floors, a bar, and games like pool. It was packed the night we went so we had to use the top dance floor; the bottom one was definitely larger and better!
And of course, Yale is a gorgeous university. Unlike other universities, it exists within the city. Although you can sense where the school ends and city begins, it's not clear. The school is built in blocks and residents of the city walk through the school all the time. Apparently, it's not really a safe city?
