I've only found two, Seasons 52 and Bonefish Grill. At least the ones I have eaten in.
Neither is inexpensive, both are what I would call moderate. The interesting thing is that Bonefish Grill is much better than it's stable mates Outback Steakhouse and Carabba's Italian Grill. The same corporation also operates Fleming's steakhouses, but I have never eaten in one.
Anyone else found any good chain restaurants?
