San Angel and LeCellier can be fairly quiet in the early evening. Food is not bad, either. Don't let your desire for Illuminations keep you from dining at one of the Epcot resorts. Boardwalk has some really nice restaurants, as does Yacht Club and Swan/Dolphin. They are a short boat ride from Epcot, and can get you back in plenty of time to get a good viewing spot. Flying Fish is a great, albeit expensive, alternative to WS. Early, it will be quiet, the food excellent, and a nice respite from the parks.
