What establishments would be good to book to be able to dine and watch Illuminations at the same time. Any advise will be very helpful.
We just dined at La Hacienda this evening. We asked for a table seat and did not get one initially. They told us to wait 2 minutes, bussed one for us and we were then seated at a window. Fantastic view of Illuminations from very high arched windows. I don't think a window seat was necessary in the main room. All tables had a view. They will rush your dinner but we didn't go with the rush. We took it very slowly with drinks, then appetizer, then slowly got around to order dinner. 7:30 reservations.
We have 7:45pm reservations here on our arrival day and to celebrate my son's birthday dinner. I am hoping we can get a table with a view and plan to have a cake for him after dinner. My kids are s-l-o-w eaters so we should be able to see illuminations.
You can also get an outside seat at the Cantina San Angel, there is a terrace there, and they were open in the evening.

The food was excellent, service was superb.
