My favorites in that neighborhood are Punch, Park Avenue Bistro, and Eleven Madison Park. Check web sites or Menupages to see if they fit your price range.
You're mixing up to restaurants: Los Dos Molinos, a tex-mex place on 18th and Dos Caminos, a Mexican/new American on Park South. The latter is better for a drink, which I think you meant.
What kind of food and what price range? There are a number of good places in the area like Giorgio's of Gramercy, Casa Mono, Giorgio's of Gramercy, Via Emilia, Shake Shack, etc.
