Chicgail, not to be argumentative, but you're sort of missing the point. We all know there are better places in Evanston, but the OP's mom
specifically asked to go there - this isn't the time to get creative. Have a salad, some tortilla soup, a burger, a nice dessert, and see a movie, and you keep mom happy. If she wanted to go to, say, Oceanique, or Trattoria DOC, she would have asked!
Riddlemay, I occasionally have the same problem with the parking garage - it seems to be configured to confuse. What's more embarassing is that I/we use it frequently - the Customary Dining Companion loves the Evanston GooglePlex's auditorium seating and interesting choice of movies, and I use it EVERY SINGLE &*?! SATURDAY during farmer's market season. You're not alone!
