I've tried E & R, at Church & East 10th (near CIA) before and tried their limbi - the conch dish - and wasn't crazy about it. I went there yesterday again and had the pork griyo - sort of like chicarrones, and I was with someone who had the oxtail. The oxtail was better: it was tender. Both were better when I added the pilkis (sp?), a very spicy sauce that brought out the taste of the meat nicely. Came with rice and beans and a salad, both of which were fine, although nothing special.
One thing that was annoying was that there was a TV that was blasting a ridiculous made-for-TV-film. I guess we could have asked them to turn it down, but we didn't. FWIW, they were very nice to us there.
I've had better griyo at El Yo Yo Fritaille on Nostrand Avenue. Kombit on Flatbush is comparable as well. But if you're in the area and want some Haitian food, it's as good an option as any.
