For starters the timeliness of someone even recognizing you've entered the restaurant is about 5min. Then you get seated and perhaps 10min later someone will take an order for drinks.
Management you should really staff of and make sure your hostess, wait staff and bus services are not the same and sole individual.
The first time we came here a few months ago we ended up leaving after sipping on water for 20 min without having our order taken.
