You see a page that is too short. Knowing that you can edit it and not be a lazybones fills you with DETERMINATION.
Grillby's is a restaurant from the original story. We first get to see it at the Page 110: ''Welcome to Grillby's''. We get to see every character from the original Grillby's in there. And everyone is much creepier and meaner (WOW, what a shocking plot twist!).
After Aliza mades it to the Snowdin, Papyrus leaves her at Grillby's. And monster in there will tell her some interesting stories. The Bear Mayor will tell her, how Undyne cracked sans's skull
Then, monsters puts her on the grill, so Aliza uses her second Freebie, and Papyrus saves her.
