I usually love going to Milestone's. It can be a bit overpriced for the quality of the food but they have a great lunch special and I love the big booths and tables.
However, the last time I went, I went with my boyfriend and we had terrible service, so bad that we walked out before our meal was served. Our waiter took our order and then didn't bring us our drinks for almost half an hour, opting instead to wait on every person around us that came in, and serve them their drinks, it was like they were trying to get us to leave. Every time we tried to get his attention, he would swoop past us as if we didn't exist. I'm fairly certain it's because we were in casual wear, flip flops and carrying backpacks. Usually when I go, it's after work and I'm dressed up and I get very good service. So a word of advice: if you want to be treated well, make sure you're not wearing ripped jeans and your hair's brushed! I found it pretty disgusting and I won't be returning.
