When in Vegas I always sit here at Otto bar and eat. As others have mentioned service is always half assed but I still come and do enjoy the ambience of the Venetian St Mark Plaza. But tonight was the worst. I dine alone since it's work related and asked the hostess if i could sit at the almost empty bar. She said yes and pointed around toward back. Even though all front sests were open I said OK and walked the circle to the back. She gave me a menu and there I sat for 20 minutes. Not a bartender or waiter in sight. Finally I picked up my briefcase and walked over to Mercato where I had a great experience. Something is off and not quite right service wise at Otto. Hopefully they read Yelp and might try to improve on their shortfalls.
