I've been looking for a good Vietnamese restaurant close to the south Summerlin area. I remembered that one had opened in the shopping center near Grand Canyon and Flamingo, but couldn't remember the name of it.
After trying a number of web searches, I finally found the adjacent Sushi Tower restaurant, because Viet Bistro could not be found when I Googled a search for Vietnamese restaurants near 89135. I finally found a a "sister" Viet Bistro restaurant, which had to provide the location on Grand Canyon as well as the phone number.
I finally found the location and and the food was very good and they did a nice job on the interior of the restaurant. I wouldn't normally waste this much time looking for a restaurant, but there are no other Vietnamese restaurants within a reasonable proximity.
With the difficulty of trying to find information on this Viet Bistro location, including address and online menu, I would be a bit concerned that they may not be in business very long.
I truly wish them success and recommend them - I also have a suggestion, specifically, get a web site and some visibility so people can find and try your restaurant!
