Our family hit this place a few months ago around May and the one thing that hit me like a load of bricks was the fine print at the bottom of the menu ...
STORY TIME!!!!!
The first time I was hit with a 2 drink minimum was at Cleopatra's Barge located in the Caesar's Palace in LV circa 1990. A Bar Rescue tip is that you do better with a "2 item" minimum opposed to a "2 drink minimum". The last time I was slapped with this was at a crappy low-end topless strip joint I was dragged into by my brother in the same city a few years later. I never drank $9 (x2) bottles of beer so fast.
FF to the future where there are replicants roaming the galaxy. I am sure in that futuristic time the "$3.99 minimum per person" would be flashing and probably coming at you in 3D (3D as in part of that ritual "this time around we WILL actually make 3D a reality ... people's homes will have all their walls ensconced in 3D!!!!" Sadly, they didn't know their history.).
Which brings us full circle back to our visit and the main problem I had. Perhaps this place is hopping on a Saturday night at 12AM like say Ten Ren around the corner, but I haven't seen any similar restrictions there. Being a capitalist society I, therefore, will never go back to Go For Tea for this reason alone.
No idea if it is really enforced with all patrons - but our table was blessed with a brand new trainee employee who I am sure met a very fluent Canadian born individual in his life but never met someone like myself - so he was rather intimidated and was ultra shy. That is why I kept calling him over to help us so that if there was a "$3.99/patron limit" we would escape that this time.
My kids had the $3.99 fruit drinks - no ice (per request - though that took some work to explain it) - drinks were cold enough. The wife and I (ahem) shared a hot black tea with honey drink. Value wise it was, all the drinks appeared to be worth the $3.99, but the tea was sickly sweet. In a perfect world you would be able to say "half sweet" or at least be asked "how sweet" before you order. We were not told and the world is not perfect since everyone's version of "half sweet" is different. At Starbucks at least you can say "2 pumps" v. "less" etc.
Having gone to Ten Ren many times for their black honey tea - this is no Ten Ren. And we paid and ran out of there before the $3.99 per drink minimum police came rolling by our table ... never to come back ever again.
Washroom was clean enough; where they were making drinks - a bit of chaos and didn't appear to be all that clean IMO. We had just eaten and we didn't want any food so no comments there.
The End.
PS If you want to enforce such silliness and it is not 24/7 and not all patrons then you need to upgrade your menu to put in limits -- like "a $3.99 minimum from 11PM for groups of 6 or more". If this minimum is not enforced 24/7 - then you will lose business for sure if you do not upgrade the menu. I am sure there is a world of options including "less" or "half sweet" - but I don't frequent places with my family and adhere to minimums (save for credit card usage).
