My wife and I last visited Portland 9 years ago -- during that visit we stayed in downtown Portland and asked around for the best breakfast place. We were pointed at Mother's; since that visit, whenever we think about biscuits and gravy, Mother's is the truly memorable experience we both think about.
9 years later, we are visiting Portland once again and set off to find Mother's this morning. The only glitch if you will is that we ordered our eggs (they come with the biscuits and gravy) soft and they came firm and rubbery -- this in no way detracted from the delicious b&g but would have enhanced the overall experience.
Would we recommend? Absolutely -- one of the truly unique breakfasts we have eaten.
