East coast blackjack is the pits
The game at Foxwoods is theoretically beatable, but it is hardly worth the effort. As with any eight deck monster, you have to spread like it's going out of style, so you subject yourself to immense variance for a piddling hourly EV. Furthermore, Foxwoods is notorious for crowding its tables, so more often than not, you'll spend ten or fifteen minutes backcounting only to have the table fill up long before the count ever gets decent.
If you're a total novice, you may find Foxwoods worthwhile for practice, but otherwise I'd rather save my bankroll for trips to Vegas.
By the way, the same goes for Mohegan Slum and AC, except the Slum has even worse penetration, and AC doesn't offer surrender (although the tables are a little less crowded.)
By the way, it's tough to find nickel tables at Foxwoods and the Slum, and sometimes there aren't any ten dollar tables either.
