Not family friendly

We visited this restaurant with two young children. We had not booked a table and understand it is busy and run the risk that there is nothing available. When the waiter approached us his first comment was. We have no high chairs, we said ok. Then he offered us a table which was high with 4 stools at it. We had a 3 year old and 18 month with us. He just said that's it. That's all we have. The restaurant is split into two levels. This was on the upper level. In the lower level there was only one table being used. We were offered no alternate time. The attitude was take it or leave it. No accommodation for our party.
