Wow I can't believe I've never written a review for this place! Been coming here for years ever since I moved to Vegas and my co-workers took me here on my first day. Sonio's serves a variety of foods including rotissierie chicken, salads in ginormous bowls, 2 lb burritos and Chicago style Italian beef and sausage. Uncle Teddy, the owner, is originally from Chicago and if you're lucky he'll stop by your table to chat. They are only open from 11 am to 5:30 pm on weekdays mainly to serve the downtown business lunch crowd, and the staff here seems to remember all their regulars which is impressive. It can get busy here during the 11 am to 1 pm lunch hours but they move quick and there's never too long a wait before a table clears up.
I typically like to get the Chinese chicken salad, Chicago style hot dogs, Italian sausage or a combo sandwich. The Chinese chicken salad comes w/ the shredded rotissierie chicken that they roast daily, mandarin oranges and a light vinagrette dressing among other things and is overall a refreshing and filling salad especially with the portions they give here. Their Chicago style foods like the Italian beef/sausage/combo sandwich tastes even better with a side of giardiniera or G as they call it here, although it does cost a little extra.
They sometimes will have a special item that they made just for that day which is nice if you want something different. Some of the specials I've seen are lasagna or meatball subs. I've recommended this place to several friends who are not Yelpers but all of them now love this place. It's conveniently located if you work in the area and serve up great food that is made to order and comes out fast and fresh.
