LV- Tropicana and Pecos Recs
Also near Sushi on Trop is a Mexican place called Aye Jose Tacos! They have good handmade food, I really like the tacos lingua, and they are open twenty four hours I believe. Also, right on the corner of Tropicana and Pecos is a Sunflower grocery store. They have decent prepared foods and solid produce offerings.
If you are a sushi fan, Sushi on Trop (2625 East Tropicana) has been consistent for a lot of years. For old-school Italian there is Casa di Amore (2850 East Tropicana), and for a little different Italian flair The Pasta Shop (2495 East Tropicana), although the latter is only open for dinner now. Those are all within a short walk of where you will be, along with a plethora of the usual fast food options.
