Rock Bottom seems to be hit, or miss. They have a pretty decent menu with a variety of items. Their happy hours is sort of ho-hum for me. There's not really a lot of good deals to be had, but beers are relatively well priced even when not on happy hour.
I had gotten two vouchers from restaurant.com and used those on two separate occasions. The first time I got the prime rib, and though I was excited to order it, I wasn't excited to finish it. It tasted as thought it had been cooked too long and there was very little flavor or moisture remaining in the meat.
However, still having another coupon I returned a second time. The second experience I ordered a steak. My wife ordered on also. I ordered mine the house default which is a little bit between medium and medium rare and it was delicious. Well-seasoned and cooked perfectly. My wife ordered hers more well done and it came out very well done. The flavor was not great, even for her. I realize that it goes without saying that it is usually best to order what the kitchen is good at doing, but be cautious in ordering things well done or you might get it really well done. We had chips which are rather cheap and they come with a sufficient serving size and decent salsa. If you like hefeweizens they have a great wit-bier that tastes similar to blue-moon with a greater serving of cloves. It tastes good and I was a fan.
