Because there are so many overwhelmingly positive reviews of Mert's, there isn't too much I can write about that hasn't been already covered. In the simplest terms: The food is very good, but it does a get a little busy on the weekends, and it isn't cheap.
I've ate at Mert's three times, and I haven't had a bad meal yet. Their salmon patties are great alone, but put their remoulade sauce on it and it's perfect, seriously! Their catfish is nicely breaded and flaky, and their sides are equally wonderful too. I've tried most of them and they're all spectacular. Their soul sampler appetizer includes a soul roll, chicken tenders, and bbq ribs. Delicious, but a whopping $12. Don't expect to eat at Mert's for less than $25 for two people!
