You'll definitely be eating here if you come to Vegas. It's open 24/7 and great for those late night bites. It's also pretty cheap compared to everything else around you. My friends ate here 3 times for our 4 day stay in Vegas hah.
For the sandwiches I would recommend getting the Montagu. Super good toasty and cheesy! Although I don't think a full sandwich is enough for a meal for some people.
