The only time I had a bad Hermolis meal was a month after Rosh hashonoh, i got an old meal with Tzimmes etc. on the same trip i got an excellent hamasbia meal. Usually, it’s the opposite, although Hamasbia has improved 200000% recently.
Rabbi Emanuel in Montreal is working on something, there was an article in Mishpacha about it, but I will say that Hermolis are the market leader in this.
