Since there's not much that's close to Signature, Delights would be your only choice if you didn't feel like traveling far to grab a bite. Food is ok along with a decent selection for breakfast & lunch but the service is slowwwwww. Had ordered 2 sandwiches that took 25 mins to come out. The place had 4 people in it.
Prices are a bit high but it's Vegas. 4 dollars for Fiji water? Jeebus. They also have beer & wine here. The place sits about 15 to 25.
