Josh Groban's residency at The Colosseum at Caesars Palace opens October 2, 2026, with multiple dates throughout the month. The Colosseum sits inside Caesars Palace at 3570 S Las Vegas Blvd. Rock N' Potato is at 3785 S Las Vegas Blvd, inside Showcase Mall on the second floor. That is steps away on the same boulevard, no rideshare required. Counter service means no reservation, no table wait, and no check to flag down before you need to head up the Strip to your seats. For a full look at the neighborhood, see the complete guide to food near Caesars Palace Las Vegas.
Rock N' Potato is a rock-and-roll food court restaurant built around loaded baked potatoes, birria, lobster rolls, and comfort dishes that hold up on a night out. The prices are honest, the portions are generous, and nothing on the menu requires a table you booked two weeks out.
The pre-show dinner window before an evening Colosseum show
Evening shows at The Colosseum typically put the pre-show dinner window in the 5:00pm to 7:00pm range. That window works cleanly with counter service: you walk up, order, eat, and leave when you are ready. No server to wait for, no check to split against a hard door time. A comfortable pre-show meal at a counter runs 30 to 45 minutes, which leaves you time to walk back up Las Vegas Blvd to Caesars Palace, clear the entry queue, and be settled before the house lights go down.
On a Thursday-night show, Rock N' Potato is open until 11:30pm, so the post-show window is covered as well. On Friday and Saturday nights the counter stays open until 1:00am. Whichever October date you have tickets for, the hours work in both directions: dinner before the show or a late meal after.
What to order before the show
Lobster Roll $16.95
Chilled lobster on a toasted split-top bun. This is the pre-show order for anyone who wants something genuinely good without the hotel restaurant price tag. It is fast, clean, and the kind of dish that makes the stop worth making entirely on its own. A comparable plate at a sit-down restaurant on the Strip routinely runs twice the price on a show night.
Fleetwood Mac $20.95
The signature loaded baked potato. Fully loaded, completely filling, and the dish Rock N' Potato is built around. If you want one item that carries you through an entire Colosseum performance without a second thought, this is it. The comfort centerpiece of the menu and a strong argument for making Showcase Mall the stop before any big show on the Strip.
Birria King $16.95
Slow-braised Angus beef birria on a toasted brioche bun with Monterey Jack and a consomme dip on the side. The alternative for anyone who wants something richer and more substantial. A real, filling meal in a handheld format, built for a night out. Order this if you want something that requires zero effort to eat and delivers on every count.
Fruity Pebbles Cheesecake $8.95
The dessert people come back for. Bright, indulgent, and exactly the kind of finishing touch a pre-show dinner needs. Under $9 and genuinely worth ordering every time. The detail that makes Rock N' Potato a different stop than anything else in this stretch of Las Vegas Blvd.

After the show: still open when you walk back down
Josh Groban's October 2026 dates at The Colosseum will include Thursday, Friday, and Saturday nights throughout the month. Rock N' Potato is open until 11:30pm Monday through Thursday and until 1:00am Friday through Sunday. If the show runs long or you would rather eat after than before, the counter is still going when you come back down Las Vegas Blvd. Counter service at 11:00pm works exactly the same as counter service at 6:00pm. No reservation, no waiting to be seated, no surge-priced ride to find somewhere still open.
