Rosa Mexicano’s Boston location formerly opens for dinner today in the Seaport District. They will start serving lunch next Monday, May 14th.
The inside of the restaurant is large, well decorated (complete with their signature Aculpoco Divers water feature) and offers space for private functions as well as a nice patio with views of Boston harbor. 
The menu is comprised of Starters, Snacks & Ceviches that mostly range from $12-$14; Tacos vary from $16-$20; and Main Plates are $17-$29. When I was at Rosa Mexicano earlier this week we had a limited tasting menu, but there were enough options to provide a good idea of what to expect. If our service is any indication of this location, patrons will be well tended to by an eager and friendly waitstaff that is knowledgeable of the menu and not afraid to offer suggestions.
Shown above was my favorite cocktail: La Sandia ($11) fresh muddled watermelon, rosemary simple syrup, tequila and fresh lemon; guacamole made table side to order ($14); Pescado de Baja Tacos ($16.50) and Enchilada de Jaiba ($23.50). The fish tacos I ordered was agreed by all to be the best plate. If you decide to order the fresh guacamole (and I do suggest you try it) then skip having a starter unless you have a large appetite otherwise you will leave overly stuffed.
Rosa Mexicano will be a popular place, but it has plenty of competition with a tequila cantina down the road at Liberty Wharf. However, there is enough business for both to succeed and I expect both shall.
Rosa Mexicano is at 155 Seaport Blvd — (617) 476-6122
