How about ...? どう
To ask the state of something (how something is doing) use the useful dou (desu ka).You can used it with or without the final 'desu ka' in conversation.
saikin wa dou desu ka?
How's it going recently?
ko-hi- wa dou?
How's the coffee? or it could mean How about some coffee?
tenki yohou wa dou?
How's the weather forecast looking?
Of course when the context is understood you can simply say, 'dou' (Like returning from a doctor's appointment, or after your friend gets off an important phone call)
