Used to love this place! Food was always excellent...

Used to love this place! Food was always excellent in the past. The last time we were there the food was bitter and extremely spicy. This was not normal. We visit this restaurant once a month and I always order the same vegan plate (because it's the only vegan dish available) so I know what to expect. Last visit my dish was not the same...not yummy...not full of flavor...just butter and extremely spicy hot. I like some heat to my food but it was like the whole bottle of cayenne was dropped in the pot!
Very disappointed.
