Scheduled my birthday dinner at Altius 6 weeks ago . Me and my husband have recommended this restaurant and have spent thousands of dollars in this establishment . My boys drove in from out of town and we showed up for our 6:45 reservation . We were dressed very appropriately for a Pittsburgh restaurant . We were told that our dress code was unacceptable and we could sit in the bar and not the restaurant , so we left and went to The Grand Concourse . My main complaint is if you have a strict dress policy , please inform your guests about this policy prior to them showing up for the reservation . We received a confirmation phone call the day before . How hard would it be to explain that everyone must be in pants ? Didn't happen . I was looking forward to this dinner for weeks . I thought my birthday was ruined , but Grand Concourse was excellent . Your hostess was rude and didn't care that our plans were ruined . Will never recommend this place again and will never be back . Bad customer service and experience . Oh well , they lost $400 dollar ticket and Grand Concourse earned it !
