Serpas True Food

I booked this restaurant for a group dinner after checking there was a vegetarian entree for me to try , 2 weeks ago there was a risotto.Last night we arrived and the menu had changed and there was now NO entree for me to eat. We talked to a staff member who said the chef would prepare me some pasta with vege and tofu. seemed like it would be Ok.
However what arrived was about a cup of undercooked over seasoned vegetables, the brussel sprouts were raw and in-edible, No tofu and No pasta.
I told the waiter I was not happy ,it was not what I had been promised. Nothing was done.
The check came and I had been charged $20 for a cup of vegetables, I complained again and they reduced the price to $16 , again double the price of a side vegetable which is basically what I got served.
For a high end restaurant having no vegetarian option is disgraceful, and rules out a portion of diners. Then when asked to provide a meal serving badly cooked vegetables as an entree is ridiculous.
I will not be returning and will warn all others not to try this place.
