Theme. ¿Hablas Español? Seven Spanish-language entries stepping across and down the grid as neatly explained by the grid-spanning reveal.
13A. Common refreshment : AGUA. I knew right away that something was afoot when this had no indication of "in Spanish" in the clue.
14D. "I'm outta here" : ADIOS. I like how "Amigo" is another of the seven themers.
28A. Chef's creation : SALSA. Once I saw this I was off to the races. I've never solved a puzzle diagonally before but the other four theme entries went in one after the other.
30D. Buddy : AMIGO
48A. Not us : OTROS. The others.
50D. Figure of veneration : SANTA. All females. The men are "San". When I can't sleep I sometimes try an alphabet run of place names, one for each San/Santa. I haven't been able to come up with a Santa "Z" yet, but there is a San Zaccaria church in Venice.
68A. Museum contents : ARTE. The Keats-Shelley memorial museum is in the house where Keats lived at the top of the Spanish Steps.
and the reveal:
39A. Roman landmark graphically portrayed by this puzzle's circles : THE SPANISH STEPS. Either "Scalinata di Trinità dei Monti" or "Scalina Spagna" in Italian depending on who you ask. You need to get up early to see them this devoid of people:
Buenos dias amigos y amigas! Steve here with Jeffrey's quick Spanish 101 quiz. A neat theme and a tidy grid with only one entry I wished wasn't there (I'm looking at you, S.F. FAN). There's a lot of unusual or unique fill; the whole puzzle feels very fresh. ¡Bravo!
Right then, let's see what else we've got. Ándale!

64. Chaucer narrative told by Huberd, with "The" : FRIAR'S TALE. He was mean about a summoner, and so the summoner told a mean tale about a Friar in turn. We read the Canterbury Tales at school, and to the credit of all concerned, our textbook was unexpurgated. It was a lot of fun translating the rude bits.
