I was always under the impression that the mandatory service fees (like for groups of x or more) was just a way to make sure that the wait staff don't get stiffed. If the service fee is 20%, I just tip 0% unless I feel inclined to tip more on top of that.

That's the interpretation I'm going with. Here, though, there are quite a few restaurants that add a service fee to all dining. If you eat there alone, you're getting a 20% fee.

It's worth asking if the service fee is actually a gratuity or not. If it's not listed as a gratuity, then legally the owner can be taking a cut.

If it’s not a tip, that should be illegal as hell. It’s just a way to have higher prices without advertising them as higher up front.
