Took my friend from Michigan to Grendel's Den in Harvard Square expecting to have somewhat of a decent experience for cheap. We went during their noted "half-price" hours - as in, the food bill is half-off if you purchase a drink.
The waitress was very rude and sullen. I realize that they place was probably understaffed that night, but such blatant rudeness is inexcusable. My Greek salad with steak tips was dry and uninspiring, and my simple request for a piece of bread was ignored. The tomato soup was a greasy bowl of something that tasted like Spaggetti-Os sauce. Two other times our waitress ignored or forgot our requests, and walked by three times even after we'd tried to get her attention. The check took 20 minutes to prepare.
Not very impressed.
