In my opinion, Murray Hill has to be one of the worst Chowhoundish areas for good food. That's why it was a pleasure to dine at a new restaurant called Ethos on Third Avenue between 33rd & 34th Street (212) 252-1972. I'd read earlier that the chef had worked at Roumeli (sp) in Astoria.
This is a comfortable restaurant, moderately priced although a bit too brightly lit for my taste. There are several booths for two, some for four, banquettes along one wall and tables in the front and middle of the room. It is definitely not a diner with 800 items on the menu. Wait staff are very polite and attentive. They sell fresh fish by the pound and grill it to order. There are also dishes like shrimp and salmon steak ($15) that are not priced by the pound. The salads and appetizers look really delicious too. Last week I had fresh grilled sardines that came with a side dish of vegies and another time I had the grilled salmon steak which was a generous portion and delicious. They also serve steak and chops that looked good on other tables.
It's great to find something in a neighborhood that basically has generic Italian restaurants and pubs. If you're in this area definitely give it a try.
