LongHorn steakhouse is a staple chain that's always been very good at service, and their food.
I recently went during a rush hour on Saturday. I recommend calling ahead to get on the list beforehand, it is VERY helpful.
All the waiters are very knowledgeable and very delightful to deal with. The only complaint I have is that they DROWN all their courses in their respective sauces. Always ask for it on the side!
