I ate breakfast at Joseph's Two, on Main Street in Waltham, twice this weekend, and thoroughly enjoyed it both times. I ordered the "hungryman" breakfast both mornings, which for $6.95 offers three eggs, bacon, sausage, toast, potatoes and a short stack of pancakes (I paid an 85 cent upcharge for the blueberry pancakes). Coffee may be included too; I don't remember.
Don't get me wrong. This breakfast almost certainly doesn't rival what you'd get (albeit for $40) at Henrietta's Table (see the nice writeup of Henrietta's brunch below), but given the price, this was a classic chowhound experience.
Certainly some things could be improved: the first morning I ordered scrambled eggs, which came out overcooked and looking more like an egg pancake than scrambled eggs. The next morning's eggs over easy were a better choice. Also, the potatoes are fine, but nothing special.
The highlight of the meal was the blueberry pancakes. The pancakes themselves were light and delicious. And although I sincerely doubt the blueberries were fresh (it is March, after all), they probably were fresh frozen, which probably stands up to the heat of the griddle better than fresh anyhow. These were truly great blueberry pancakes. As these types of places tend to do, Joseph's serves the pancakes with about a half a pound of melting butter and a generous amount of powdered sugar on top, so make sure to specify if you don't want this. (On the topic of special orders, I observed at other tables that they were very accommodating about making substitutions -- I heard the waitress offer one person "double bacon" when the person said she didn't want the sausage that came with the hungryman -- and handling special requests.)
Don't confuse breakfast at this place with breakfast at The Four Seasons, but it is thoroughly satisfying and certainly a better value. Also, don't let the lines that sometimes form on the weekends scare you away: the line moves very fast.
