We just got one in our town. The excitement was truly amazing. People have been trying to get one here for years, so now the parking lot is packed every day. I'm finding it a great resource for "cutting corners" meals - we've been making shrimp pasta with the cooked frozen shrimp and using the tater tots and dumplings to round out meals.
I love TJs for that kind of stuff. Also, their prices on things like nuts, olive oil, and cereal are incredible. Some stuff isn't great to buy there (I had their cream cheese this morning and it just doesn't compare to Philly), but in general I just love it there.
