I'm looking for an elegant Mother's Day brunch suitable for taking an elderly grandmother out. Price is no object; I'm primarily looking for a place that's really nice and will impress her with good food as well as a nice atmosphere. Food should be reasonably mainstream - granny doesn't do spicy - so no Indian, Thai, Mexican, etc. The location should be within roughly a half hour's drive from the intersection of 3, 46, and the Parkway in Clifton; as long as it's not past 287, it's probably okay.
I've looked at the web menu for the regular buffet Sunday brunch at the Terrace at the Hilton in Short Hills, and it sounds like just the sort of thing I'm looking for - anybody been? I also see that Amanda's in Hoboken has received awards as the best Sunday brunch in Jersey, and it has a nice menu too (a la carte) - again, anybody been? I know she's been numerous times to the Manor and the Highlawn Pavilion, so those might not be my first choice, but I'll be keeping them in mind. I'm open to additional suggestions, so feel free to mention any place else you think would be suitable.
Also, if there are any "gotchas" involved, please mention them. (For example, I know in some cities, Sunday brunch books up many months in advance.)
Thanks in advance for any help you can provide!
