i am looking for a restaurant in the center of town that serves european food .
user
there are several that suit your needs . any preferences on price range ?
assistant
moderate price range , please .
user
the 4 matching restaurant -s are hotel du vin and bistro , galleria , de luca cucina and bar , and riverside brasserie .
assistant
perfect ! can you please book a table for 3 people at galleria for me on monday at 16:30 ?
user
booking was unsuccessful . would you like to book another day or time slot ? or perhaps another of the restaurant choices for the same booking information ?
assistant
let s try for 15:30 and can i get a reference number please ?
user
ok . that worked . it is booked and your reference number is qbvp0zv2 .
assistant
great ! i also need a guesthouse with free wifi . something moderate -ly priced , and i do not care about parking .
user
there are fourteen different options for your guesthouse . is there a specific area you would like to be in ? how about the star rating ?
assistant
i do not have any preference . could you just pick something and book 5 nights for 3 people beginning on monday ?
user
let s go with acorn guest house . unfortunately , that booking was unsuccessful . want me to try something else ?
assistant
instead of 3 nights how about 2 nights ?
user
there seems to be an error . can you please restate your preferred number of nights , the day you will arrive , and the number in your party ?
assistant
certainly . 2 nights , 3 people , and i'll need that room starting monday .
user
great ! your booking was successful . the reference number is twu9em7u . do you need help with anything else ?
assistant
i do not . thanks so much .
