Ibiza Tapas & Wine Bar, which has locations in Hamden, CT & Northampton, MA, is opening a new location in Danbury this Saturday, January 26. They're having an open house this Friday the 25th from noon until 10PM with free food (assorted tapas, etc. from their menu) & wine.
They're located on the west side of Danbury at 93 Mill Plain Rd (Rt. 6/202), about 1/2 mile east of I-84 Exit 2 on the north side of the road in a perpendicular strip mall that's fronted by the Panda House and also contains the Kibberia.
From many visits to the Hamden location, I strongly recommend giving it a try. If you've been to Hamden, the Danbury location has a similar decor, but is easily twice the size. If their hours are similar to the other locations, they'll only be open for dinner, but with all the WCSU students & faculty nearby, maybe that could change.
