I've been to Mitzi's a whole bunch of times, but the past two times I tried to go there this summer/fall I just walked out.
The service is just awful. No one who works there knows what is going on. One time I was there I was told to wait 15 mins for a table outside. So I sat on the bench outside and waited for about 30 mins. I went back inside, and at that point, said I would take any table because I was hungry (and there were 5-6 free tables inside). So I sat down inside. 20 minutes later I walked about because no one could bother to come by and take my order. I wasted nearly an hour waiting for a table, and finally gave up and went down the street to Easy.
The second time I opted to take an indoor table and was told that they were short staffed so I would have to wait 15 minutes to order. After 15 minutes I asked if I could order and was told no, because she wasn't sure how long it was going to take. I waited another 10-15 minutes and then just gave up.
The food is great, but having to wait upwards of an hour and dealing with the staff is mighty stressful on a Sunday morning.
