As anticipation builds for all the new restaurants under construction at Westfield Montgomery Mall, we hear that MET Bethesda is set for an unofficial opening on Saturday, Nov. 15. House specialties will include avocados stuffed with Maryland crab, a “Char Bar” of skewered meats and vegetables, and a selection of raw and cooked New England seafood — plus a martini bar with 30 flavors on tap. This will be the fifth location for Boston-based MET Restaurant Group, and the first outside of Massachusetts.
