Well, Foxwoods has a HUGE poker room, 100+ tables I believe. The S&Gs start at 10AM or so, and they have MTTs daily. The buyins are higher than I'm prepared to pay. Also, when big tournaments are coming up, they have some pretty decent and affordable satellites.
Mohegan Sun will have a REAL poker room when their new Casino is built. For now they have some electronic poker tables. I saw a 1/2 NL ring game playing on a table and I know they also have some S&Gs, but there wasn't one running when I was there. They also had a few heads up tables but they weren't being used at the time. If I had known about the 1/2 NL game I would have played; however, I was on my way out of the casino when I saw it.
